RNFL asymmetry is the difference between the RNFL of the left and right eyes. In healthy patients, one study (2008, n=109) found asymmetry to be typically between 0-8μm, but occasionally higher, with average asymmetry of c.3μm at age 25 rising to 5μm at age 60. [ 4 ]
The deviation map reveals the location and magnitude of RNFL thinning relative to a normal value. This normal value was generated as an average of people from various cultures. Defects are colour-coded based on probability of normality (e.g. yellow means that the probability is below 5% of that RNFL at that location is normal).
Retinal microvascular disease is noninflammatory and resembles that of diabetic retinopathy. This leads to partial or complete vision loss. [6] Headaches due to multiple factors including brain lesions, edema, and papilledema. Mental confusion, loss of cognitive function, loss of memory, slowing of speech and hemiparesis due to brain lesions.
In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution.

How Much Hair Loss Is Normal for Women? Stacey Colino. July 12, 2024 at 10:43 AM ... It’s normal to lose 50 to 150 hairs per day. That may seem like a lot, but most people have about 100,000 ...
The normal distribution, also called the Gaussian or the bell curve. It is ubiquitous in nature and statistics due to the central limit theorem: every variable that can be modelled as a sum of many small independent, identically distributed variables with finite mean and variance is approximately normal. The normal-exponential-gamma distribution
It affects women more than men due to the sharp fall in estrogen production that follows menopause. [196] Globally, it is estimated that 21.2% of women and 6.3% of men over the age of 50 have osteoporosis, corresponding to a total of around 500 million people worldwide. [197] About 15% of Caucasians in their 50s and 70% of those over 80 are ...
